- Be it known that I, SHIGEfrAno YAMADA, a .subject of .thev EmperorofJapan, resid; ing at Honolulu, in the county'of Honolulu and Territory of Hawaii, U. Si. A., have invented certainfnew and useful Improvements 1in .Twine-Cuttina Devices, of which the following is a Vspeci cation.-

The inventionA relates to improvements in cord'or twine cutting devices.

It is an object of the invention to provide a cord or twine cutting machinewhichy is of a simple construction, and .one that is capable of-general use where-ver itis desirableto sever the cord or twine by amachine. The invention hasparticular appli-y cation to the provision of a' machine wherein a supply. of twine or cord in ball form "is automatically advanced under a movable cutting` blade where the cord or twine is sheared and the end of the cord then slightly advanced, so as to provide a portion to be conveniently grasped for a second operation.

More particularly-the invention comprises a portable apparatus which may be placed upon -a store counter or the like, having supporting means'for-a ballor balls of cord or twine, adapted to be fed through the machine. ally pressed handle serve to sever lthe strands, `and after severance thereof, the cord is'advanced automatically so as to provide exposed end portions which maybe grasped for a subsequent use "when the cutters are to be again operated. :Thispermits a user to rapidly obtainia strand or strands of cord or twinefof a desired length, to instantly sever the same, and to automatically advance thel ends ofthe balls so thaty said A 1 uponthefframe 7 while thegrip. 14,'-as will ends are exposed fora subsequent operation.

f The inventionconsists in improved structures-and combinations yfor accomplishin in compact vformation and areoperated upon 1 .of this invention.. In ythedravvings, Y Figure l represents a4 viewy looking at. one side ofthe device.`

Inthe accompanying drawings l".l have disclosed the preferred embodiment of my invention, but it Willbefunderstood that the f `construction and. arrangement of parts may be alteredwithoutdeparting from Ithe spirit moved. V Y

Referring now more particularly. tothe drawings wherein like reference 'numerals designates a casing vadapted to receive vthe various parts of thecuttmg andffeedin mechanism, which casmgpmaybe Vcompose the .operating mechanism of the device for feeding the cord and severing, thesame to more fullylh'ereinafter described.`V Mounted within thecasingl is a base4, i Ahaving upstanding parts receiving the'meshing gears 5 and 6, Journaledz in, said parts,

'The'reciprocating frame 7 merely consists of separated'bars,;provided with a vertical space 18 thereiminte'rmedi ate their ends adapted to receive thecrank 100 arm '19 operating olf ofthe shaft of the. gear 6, which'crank arm* effects a forwardV andrearwardmotion' off the frame during its oscillation, all of which'will" be more fully hereinafterdescribed.' f`

From around these .p'iilil'eys` the string passes horizontally under the tension springs 25, then through apertures 26 in .the strngleads- Before reaching the apertures in the string leads, the ,stringsy are of course caused toI Ypass through apertures in the cutter frame i 27.., which cutter 'frame Consists 'of Suitable grip 1.6?. HOWGVQR after the String Separated. Slide bars mountedupon a Support, nndhaving mquntedtherein cutting knives 2T attached to a cutting-bar, rwhich cutting bar at itsv outer end is fashioned with a rank arm. 2.6i adapted t0 be engaged by an operatingmember to sliift rthe entire .cuttingframeagainst the tension 'of the springs 27a So,.thatsad knives 2,77 are moved, across ,the pathl ofthe strings, engaging and serving1 fsaidstrings, theknives being returned to their nenial; Ostion by the resilient springs cooperating therewitln and engaging .iilfaeo a statenar'y .partei the machine.

leaetimte the? Cutters or knives. and like wiselfeed the strings, there is disposed within theasnsa .reciprocating push. rod ,28, fmeunted wthinthe Cylinder 28", and. having the. teeth` of the gear 5, This lever is yalso kp;@vided with anoffset part 29, having an aperturepassing ,throughl the standard 30, whnaoset. part Causes', a depress@ of the spring -31Whn .the hand Operating rod 28 is depressed, thereby causing said rodA yt0 be eutonatsally retured .te its normali .Posi- It will benbserved hatdue.tothek gear arrangement 5. andk what whenthe r0df28 L sfdenrfessed, theknivesofcoufse are shifted SOas t0 out thestring or strings` lying in .the/path theteot During this dpwnwerd lentement 0f.

grip 16 forwardly, whichv advances the string or stringe so that the severed ends icient distance until they project through the openings in the string leads 26, whereby they may be'grasped .by the, user of the device when it is again necessary to operate .the machine. It will be observed that while the string grip 16 is operable, that the string grip lliv *is stationary, and that said grip prevents the string from being moved rearwardly when the ygrip 16 is being shifted in a rear direction by the crank arm 19. This grip merely slides from the string and when the grip, is again caused to travel in a forward direction, it grips the string and advances the same .the length kof its move:- ment, which is sufficient to push the severed ends out through ythe string leads 26. 'From the foregoing it will' be apparent that `the operation of the hand rod 28 upon'its `downward sti-oke causes the wedge-shaped kmember 32 to engage the ycrank arm 26a, causing an actuation oft the -knives 27 in the path of; the string, severing said string. These crank arms are constructed so that one moves in one direction and theotherin an opposite direction upon the engagement of the beveled sides ofthe wedge-shaped? Vmember 32 Causing an operation of the lrnil'ves.
